Abstract
The utility model relates to a valve provided with a magnetic coupling device which is composed of external magnetic steel, internal magnetic steel, a separation sleeve and a connecting frame. The start of the valve is implemented by the magnetic transmission of the internal and the external magnetic steel, with small start and stop resistance. The magnetic coupling device makes the valve form a fully sealed structure, which fundamentally solves the problem of medium leakage. The utility model becomes a fully-closed corrosion-resistance valve after lined with flurine plastic, and therefore, the valve with the magnetic coupling device is a great breakthrough on valve structural design. The valve is more suitable to be installed on pipelines conveying flammable, explosive, toxic and corrosive medium.
Description
The utility model relates to a kind of valve, particularly a kind of stop valve.
Known valve, no matter be manually-operated gate or electric valve, structurally all have valve body, spool, valve rod, seal arrangement and starting drive, wherein seal arrangement all adopts packing seal at present, in use there are two problems in this packing seal: the one, and filler need compress, cause the keying resistance of this valve big, the 2nd, after the filler wearing and tearing, the dielectric leakage phenomenon is inevitable.
It is little that the purpose of this utility model provides a kind of keying resistance, the hermetically sealed leak free valve of medium.
Solving main points of the present utility model is that described seal arrangement adopts magnetic coupling device, this device is made up of outer steel, interior magnet steel, separation sleeve and hitch, outer steel places outer steel chamber And to connect with the startup axle of starting drive, magnet steel chamber And formed screw pair with valve rod in interior magnet steel placed, and valve rod is provided with the axial displacement guide mechanism of being made up of square shaft and side's cover.
Below in conjunction with accompanying drawing, content of the present utility model is described in further detail.
Fig. 1: manually-operated gate structural drawing with magnetic coupling device;
Fig. 2: electric valve structural drawing with magnetic coupling device;
As shown in the figure, this valve with magnetic coupling device has valve body (1), spool (2), valve rod (3), magnetic coupling device and starting drive.The starting drive of manually-operated gate is made up of handwheel (4) and startup axle (5), and the starting drive of electric valve is made up of motor (6), retarder (7) and startup axle (5).Magnetic coupling device is assembled by outer steel (8), interior magnet steel (9), separation sleeve (10) and hitch (11,12), separation sleeve (10) is separated into outer steel chamber (13) and interior magnet steel chamber (14) with the magnet steel chamber, outer steel (8) places outer steel chamber (13) And to be installed on the startup axle (5) by outer steel cover (15), magnet steel chamber (14) And was inlaid on the interior magnetic steel sleeve (16) in interior magnet steel (9) placed, interior magnetic steel sleeve (16) is supported by bearing, the cuter spiral that is provided with on the same valve rod of inner bolt hole ， And (3) becomes screw pair.Valve rod (3) only pumps, and does not rotate, and for this reason, valve rod axial displacement guide mechanism is set, and is made of the square shaft (18) on the same valve rod of square cover (17) (3).Outer steel (8) has plane coupling (as Fig. 1) and cylinder coupling (as Fig. 2) two kinds with the coupled mode of interior magnet steel (9), no matter be manually-operated gate or electric valve, these two kinds of magnetic coupling structures all can adopt.
Carry aggressive medium with this valve with magnetic coupling device, the steel member can select for use stainless steel to make, also can be at the internal surface of valve body (1) and in placing the component surface in magnet steel chamber (14) establish fluoroplastics lining nexine (19).
For electric valve, motor (6) should have can be according to the control circuit of the automatic stall in upper and lower dead center position of spool (2).
The keying of above-mentioned valve is that the magnetic drives by inside and outside magnet steel realizes, obviously, the keying resistance of this valve is smaller. In addition, magnetic coupling device forms hermetic valve mechanism, and the movable sealing that becomes known valve is static seal, so that there is not the leakage problem of medium in this valve, therefore, this valve is more suitable for being installed on the pipeline of carrying inflammable, explosive, poisonous medium and uses. Behind the inner lining fluoroplastics lining, becoming again and a kind ofly this shows to have the valve of magnetic coupling device than the better full-sealed corrosion-resistant valve of stainless valve corrosion resistant performance, is the important breakthrough in the valve mechanism design.
Claims (2)
1, a kind of valve that constitutes by valve body, spool, valve rod, seal arrangement and starting drive, it is characterized in that: the magnetic coupling device that described seal arrangement is made up of outer steel (8), interior magnet steel (9), separation sleeve (10) and hitch (11,12), wherein outer steel (8) places outer steel chamber (13) And to connect with the startup axle (5) of starting drive, the same valve rod of magnet steel chamber (14) And (3) formed screw pair in interior magnet steel (9) placed, and valve rod (3) is provided with the axial displacement guide mechanism of being made up of square shaft (18) and side's cover (17).
2, valve according to claim 1 is characterized in that: the internal surface of valve body (1) is provided with fluoroplastics lining nexine (19) with the component surface that places interior magnet steel chamber (14).
